== HBase Shell Background ==
- I expect Hadoop + Hbase to handle sparsity and data explosion very well in near future. Moreover, i believe the design of the multi-dimensional map structure and the 3d space model of the data are optimized for rapid ad-hoc information retrieval in any orientation, as well as for fast, flexible calculation and transformation of raw data based on formulaic relationships. It is advantageous with respect to Analysis Processing

Moreover, i believe the design of the multi-dimensional map structure and the 3d space model of the data are optimized for rapid ad-hoc information retrieval in any orientation, as well as for fast, flexible calculation and transformation of raw data based on formulaic relationships. It is advantageous with respect to '''Analysis Processing'''
as it allows users to easily formulate complex queries, and filter or slice data into meaningful subsets, among other things.
=== Rationale ===
It will probably take a while for Hadoop + HBase to provide reliable real-time service like other DBMS.
